Due to the relatively large increase in the coefficient of thermal expansion, the thermal shock stability is reduced. It can be used to manufacture insulating ceramic parts for ultra-high frequency and high-power electric vacuum devices, as well as ceramic shells and various ceramic substrates for vacuum capacitors.

Jinzhou Yunxing Industrial Ceramics Co., Ltd. Due to the increase in business volume and product categories, the company built a new factory. Now the appearance of the office building of the new factory has been completed.

(1) Easy to wash and keep clean. The glazed surface of the alumina ceramic crucible is bright and delicate, and it is easy to wash away after being contaminated. (2) Porcelain has very few pores and low water absorption. Use alumina ceramic crucible to store the solution. After the mouth is tightly sealed, it can prevent the solution from volatilization, penetration and external bacteria.

The current application of alumina ceramics in the market has far exceeded our expectations. The overall application of alumina ceramics is becoming more and more extensive, because it can not only meet the needs of our daily life, but also meet the needs of some special properties, although The application of alumina ceramics in modern society has been very extensive, so what are the main principles for choosing high-quality alumina ceramic rods? The following is introduced by the staff of Jinzhou Yunxing Industrial Ceramics Factory:

The ceramic material developed earlier is alumina ceramics. This material is resistant to high temperature and corrosion. It is an excellent and commonly used material. The material can be used to replace metal substances and extend the service life of the equipment. Increase the use of power.

Alumina ceramic tube sintering is a key stage of ceramic preparation, and the sintering atmosphere has a great influence on the preparation of ceramic materials. Too high sintering temperature or too long holding time will promote crystal growth, so that the fine raw materials will develop into coarse grains at high temperature, and the amount of liquid phase will increase. This will not only decrease the strength, but also weaken the wear resistance. Of course, if the temperature is too low, the sintered body will not be dense, and the wear resistance of the product will not be good.

Production practice and a large number of studies show that: low porosity, high density alumina ceramics have excellent structural properties. High density means that the crystal grains in the ceramic body are tightly arranged, and it is not easy to form destructive breakthrough points when subjected to external loads or corrosive substances.

In order to obtain alumina ceramic materials with high wear resistance, not only should it be considered to have high density, flexural and compressive strength, but also to increase its hardness and fracture toughness, and these properties are in line with the obvious characteristics of alumina ceramics. The microstructure (closed porosity, grain size, distribution of glass phase, etc.) and its wear mechanism are closely related.

Generally for not very dirty ceramic tube, cleaning is very easy, because only need to use some clean water to wash it can.Because it is very wear-resistant, so you can also use some relatively large friction cleaning tools to clean it, no matter how much you use will not cause any loss to it, so we do not have to worry about this.It's easy to clean up with a brush and some detergent.When cleaning, you can use a water gun with higher pressure to wash it, so that it will be more convenient to wash, but also more clean. I believe that many people will have used such a method.

Alumina industrial ceramics‍ material has been seen a lot, this kind of industrial ceramic material application of alumina chemical properties, but not alumina and ceramic combination, this kind of alumina ceramic material and other different materials with the same route, thermal conductivity and ductility have a great advantage.Alumina is also the chemical name of aluminum oxide (Al2O3), while the chemical composition of ceramics are usually silicon dioxide (SiO2) and calcium carbonate (CaCO3).The finishing process of alumina ceramics is powder preparation, this preparation method has high molding rate, fast working efficiency and high success rate of products.
